Description

Technical Field

[0001] The invention relates to the technical field of dust suppression equipment, and in particular to a protective device for road environmental protection construction. Background Art

[0002] When constructing a highway, usually only part of the highway is constructed while the other part is still in use. In order to prevent irrelevant personnel from entering the construction site, it is necessary to isolate the construction site from the non-construction highway. At the same time, in order to prevent a large amount of dust from the construction site from splashing onto the non-construction highway, it is necessary to install road protection devices. Existing construction protection devices cannot reduce the dust generated during the construction process, so the dust will affect the construction workers and pedestrians, that is, endanger the lives and health of the construction workers and pedestrians.

[0003] To solve the above problems, a Chinese patent with publication number CN218563278U discloses a protective device for road and bridge construction, including at least one guardrail, the guardrail includes a base, a baffle is provided on the base, the end of the baffle away from the base expands outward to form a mounting portion, the mounting portion is provided with a U-shaped groove with an opening facing the end away from the base, a water pipe is provided in the U-shaped groove, and a plurality of atomizing nozzles are provided on the water pipe along its length direction, and a connector for connecting the water pipes on the two adjacent guardrails is provided between the water pipes on the two adjacent guardrails. The device can achieve dust reduction on the construction site by setting the atomizing nozzle on the guardrail, avoiding dust pollution to the environment of roads and bridges, and ensuring the life and health of construction workers and pedestrians.

[0004] The above-mentioned device has the following problems during actual use: the water pipe is fixedly installed on the guardrail, so the atomizing nozzle is also fixedly installed on the guardrail, which results in the water mist sprayed from the atomizing nozzle only being able to reduce dust in one direction, resulting in a small range of action of the water mist, making the dust reduction of the water mist not comprehensive and sufficient, that is, the dust reduction effect is poor and the dust reduction efficiency is low; and the device cannot adjust the pressure of the water mist sprayed by the atomizing nozzle, which results in the water mist sprayed by the atomizing nozzle having a limited effective distance, so that the dust far away from the guardrail cannot be affected. Therefore, the dust reduction area is relatively limited, which cannot meet the actual construction requirements of the construction personnel and reduces the construction efficiency. Summary of the invention

[0005] The invention provides a protective device for road environmental protection construction, so as to solve the problems that the atomizing nozzle of the existing protective device has a small action range and incomplete dust reduction.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a protective device for road environmental protection construction, including a guardrail, and also including a dust reduction mechanism arranged on the guardrail; the dust reduction mechanism includes an annular water tank, an annular pipe, a plurality of dust reduction components arranged equidistantly along the circumferential direction of the annular pipe, a chamber opened in the guardrail, and a driving component for driving the annular pipe to rotate; the annular water tank is located in the chamber, and the annular water tank is fixedly connected to the chamber; a through hole is opened on the chamber, the annular pipe is slidably connected to the annular water tank, a plurality of water inlet holes are opened on the annular pipe, and a plurality of water outlet holes are opened on the annular water tank, and the water inlet holes and the water outlet holes are connected; the dust reduction component includes an atomizing nozzle, a rubber tube, an extrusion block, and a power unit for driving the extrusion block to perform vertical reciprocating motion; the atomizing nozzle is connected to the annular pipe; the rubber tube is connected to the atomizing nozzle; the rubber tube is located on the motion trajectory of the extrusion block.

[0007] The principles and advantages of this solution are:

[0008] 1. When it is necessary to construct the road, several guardrails are attached to each other in sequence and form a circle to protect the construction site; then the driving component drives the annular tube to rotate, so that the water inlet and outlet holes can be continuously and intermittently connected, so that the water in the annular water tank can flow into the annular tube, and then sprayed out through the atomizing nozzle; during the spraying of water mist by the atomizing nozzle, since the annular tube can rotate, the atomizing nozzle can make a circular motion, thereby expanding the range of action of the atomizing nozzle, enhancing the effect of the atomizing nozzle, and allowing the water mist to diffuse over a large area, ensuring that the water mist contacts more dust, thereby achieving dust reduction and improving dust reduction efficiency, that is, improving the comfort of the construction environment and protecting the life and health of construction workers and pedestrians.

[0009] 2. During the period when the atomizing nozzle sprays water mist, the extrusion block is driven by the power unit to perform vertical reciprocating motion; when the extrusion block moves vertically upward, when the extrusion block contacts the rubber tube, the extrusion block continues to move, thereby causing the rubber tube to deform; during the deformation of the rubber tube, the water outlet of the rubber tube will be squeezed and become smaller, thereby increasing the pressure in the rubber tube, that is, the water mist sprayed by the atomizing nozzle can increase the effective distance of the water mist after the rubber tube is deformed; when the extrusion block moves vertically downward, the rubber tube gradually returns to its initial state, thereby causing the effective distance of the water mist to gradually return to its initial state; therefore, through the deformation of the rubber tube, the effective distance of the water mist can be continuously adjusted, so that the water mist can contact more dust during the period when the effective distance changes, further expanding the effective range of the water mist and ensuring that the dust is more comprehensively and fully suppressed.

[0010] To sum up, through the rotation of the atomizing nozzle and the deformation of the rubber tube, the scope of action of the water mist is expanded and the effective distance of the water mist is increased, that is, the effect of the atomizing nozzle is comprehensively enhanced, making the dust reduction of the atomizing nozzle more complete and thorough, which greatly improves the environment of the construction site, reduces the harm of dust to construction workers and pedestrians, and improves the practicability of the device.

[0011] Furthermore, the dust reduction assembly also includes a blower part; the blower part includes a rotating shaft, fan blades, and a motion unit for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the annular tube; the fan blades are fixedly connected to the rotating shaft; and the water outlet of the rubber tube faces the fan blades.

[0012] The shaft is driven to rotate by the motion unit, and the fan blades rotate synchronously during the rotation of the shaft. During the rotation of the fan blades, the effective distance of the water mist and the effective range of the water mist can be further increased, so that the water mist can further contact more dust, thereby making the dust reduction effect of the water mist on the dust more significant, that is, shortening the dust reduction time and improving the dust reduction efficiency.

[0013] Moreover, during the rotation of the fan blades, the dust in the air can be dispersed, so that the dust does not accumulate, the proportion of dust in the air is reduced, and the air quality is improved; at the same time, it is beneficial to the circulation of air in the construction site and enhances the ventilation effect, that is, it increases the flow rate of water mist and dust and shortens the dust removal time.

[0014] Furthermore, it also includes a number of auxiliary components equidistantly arranged along the circumferential direction of the annular tube; the auxiliary components include a rotating shaft, a first cam, a piston cylinder, a piston block, a first spring, a water inlet pipe, a drain pipe, and a driving unit for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the annular tube; the first cam is fixedly connected to the rotating shaft; the two ends of the water inlet pipe are respectively connected to the piston cylinder and the annular tube; the piston block is slidably connected to the piston cylinder, and the first cam is against the piston block; the two ends of the first spring are respectively connected to the piston block and the piston cylinder; the drain pipe is connected to the piston cylinder, and the drain pipe is communicated with the piston cylinder.

[0015] During the movement of the annular tube, the piston cylinder moves synchronously driven by the water inlet pipe; during the movement of the piston cylinder, the rotating shaft is driven to rotate by the driving unit; during the rotation of the rotating shaft, the first cam rotates synchronously; during the rotation of the first cam, when the raised portion of the first cam abuts against the piston block, the piston block moves vertically downward, and the first spring is compressed. When the raised portion of the first cam no longer abuts against the piston block, the piston block is reset under the action of the first spring, and the piston block moves vertically upward; therefore, the piston block can perform vertical reciprocating motion.

[0016] During the vertical reciprocating motion of the piston block, the piston block can continuously pump out and discharge the water in the annular tube; during the pumping period of the piston block, the water in the annular tube flows into the piston cylinder along the water inlet pipe and is temporarily stored; during the drainage period of the piston block, the water stored in the piston cylinder is discharged along the drainage pipe.

[0017] Through the above movement, the water discharged from the drain pipe has a certain force and forms a water line, which can disperse the dust in the air, so that the dust no longer gathers in a pile, and then the dust is diffused, increasing the contact area between the water mist and the dust, so that the dust can be better reduced by the water mist and the water line, thereby enhancing the dust reduction effect and ensuring that the dust can be completely removed; and, since the piston cylinder can rotate, the range of action of the water line is expanded, ensuring that the dust in the air can be dispersed more comprehensively and fully, that is, the dust reduction time is shortened and the dust reduction efficiency is improved.

[0018] To sum up, under the joint action of the atomizing nozzle and the drainage pipe, the dust reduction effect can be comprehensively improved, ensuring that the dust in the air can be handled more thoroughly, greatly improving the working environment of the construction workers, and ensuring the life and health of the construction workers and pedestrians.

[0019] Furthermore, the auxiliary component also includes a boosting part; the boosting part includes a bidirectional screw, a guide rod, a boosting unit symmetrically arranged at both ends of the bidirectional screw along the axial direction of the bidirectional screw, and a power unit for driving the bidirectional screw to rotate; the bidirectional screw is rotatably connected to the piston cylinder; the guide rod is fixedly connected to the piston cylinder; the boosting unit includes a nut seat, a connecting block, and an arc block; the nut seat is threadedly connected to the bidirectional screw, and the nut seat is slidably connected to the guide rod; the connecting block is fixedly connected to the nut seat; the arc block is fixedly connected to the connecting block; the arc block is attached to the water outlet of the drain pipe.

[0020] The bidirectional screw is driven by the power unit to rotate forward and reverse. During the rotation of the bidirectional screw, the two nut seats can approach or move away from each other along the length direction of the guide rod; during the movement of the nut seat, the connecting block moves synchronously; during the movement of the connecting block, the arc block moves synchronously, that is, the two arc blocks can also approach or move away from each other; during the period when the two arc blocks approach each other, since the arc block is in contact with the water outlet of the drain pipe, the arc block can block a part of the water outlet of the drain pipe, until the two arc blocks are in contact, and then the two arc blocks move away from each other.

[0021] Through the above movement, while the arc block is blocking the water outlet of the drain pipe, the pressure in the drain pipe will increase, thereby making the effective distance of the water line sprayed from the drain pipe farther, so that the water line can disperse more accumulated dust, further ensuring that the dust will not accumulate together, and at the same time greatly expanding the contact area between water mist and dust, comprehensively enhancing the dust reduction effect of water mist on dust, and improving the dust reduction efficiency of dust.

[0022] Furthermore, a linkage part is provided on the nut seat; the linkage part includes a vertical block, a plurality of transverse blocks, and a linkage unit for driving the vertical block to perform vertical reciprocating motion; the vertical block is vertically slidably connected to the nut seat; a plurality of transverse blocks are equidistantly arranged along the height direction of the vertical block, and the transverse blocks are fixedly connected to the vertical blocks; the water outlet of the drain pipe is located on the movement trajectory of the transverse block.

[0023] During the movement of the nut seat, the vertical block is driven to perform vertical reciprocating motion through the linkage unit; during the movement of the vertical block, the transverse block moves synchronously; during the movement of the transverse block, when the transverse block moves to the position of the drain pipe outlet, the transverse block can slap the sprayed water line, so that the movement trajectory of the water line changes, and then the water line can make a wave-like motion of swinging up and down, so that the water line can be dispersed; after the water line is dispersed, the range of action of the water line is increased, so that the water line can disperse more dust gathered together, further expanding the contact area between dust and water mist, thereby ensuring that the dust can be dispersed more comprehensively and fully, further enhancing the dust reduction effect on dust, and improving the dust reduction efficiency.

[0024] Furthermore, the drain pipe is rotatably connected to the piston cylinder; a belt is provided between the drain pipe and the rotating shaft; and two ends of the belt are respectively sleeved on the drain pipe and the rotating shaft.

[0025] During the rotation of the rotating shaft, the drain pipe is driven to rotate by the belt; during the rotation of the drain pipe, the drain pipe has a certain centrifugal force; therefore, the water line will fly farther under the action of the centrifugal force, further expanding the scope of action of the water line, on the one hand, improving the utilization rate of the water line and enhancing the effect of the water line, on the other hand, ensuring that more accumulated dust can contact the water line, expanding the contact area between the dust, water mist and water line; that is, ensuring that the dust in the air can be handled more comprehensively and thoroughly.

[0026] To sum up, through the joint action of the arc block, the transverse block and the belt, the water outlet effect of the drain pipe can be enhanced in all directions, that is, the water outlet range of the drain pipe is expanded and the water outlet distance of the drain pipe is increased, so that the dust in the construction site can be fully affected by the drain pipe, and then ensure that the dust can be completely removed by the water mist after spreading, thereby improving the environment of the construction site and protecting the lives and health of construction workers and pedestrians.

[0027] Furthermore, the power unit includes a second cam, a slider, and a second spring; the second cam is fixedly connected to the rotating shaft; the slider is vertically slidably connected to the annular tube, the arc block is fixedly connected to the slider, and the second cam abuts against the slider; the two ends of the second spring are respectively connected to the slider and the annular tube.

[0028] During the rotation of the rotating shaft, the second cam rotates synchronously; during the rotation of the second cam, when the raised portion of the second cam abuts against the slider, the slider moves vertically upward, and the second spring is compressed. When the raised portion of the second cam no longer abuts against the slider, the slider is reset under the action of the second spring and moves vertically downward; therefore, the slider can perform vertical reciprocating motion; during the movement of the slider, the extrusion block moves synchronously.

[0029] Furthermore, it also includes an annular rack; the annular rack is fixedly connected to the guardrail; the motion unit is a first gear; the first gear is fixedly connected to the rotating shaft, and the first gear is meshed with the annular rack.

[0030] When the rotating shaft moves with the annular tube, the first gear moves synchronously; when the first gear moves, the first gear is engaged with the annular rack, so the first gear rotates; when the first gear rotates, the rotating shaft rotates synchronously, that is, the rotating shaft can rotate while making circumferential motion.

[0031] Furthermore, the driving unit is a second gear; the second gear is fixedly connected to the rotating shaft, and the first gear is meshed with the second gear.

[0032] During the rotation of the first gear, the first gear is meshed with the second gear, so that the second gear rotates. During the rotation of the second gear, the rotating shaft rotates synchronously.

[0033] Furthermore, the power unit is composed of a guide block, a rack, a third spring, and a third gear; the guide block is fixedly connected to the piston cylinder; the rack is vertically slidably connected to the guide block, and the second cam is against the rack; the two ends of the third spring are respectively connected to the rack and the guide block; the third gear is fixedly connected to the bidirectional screw, and the third gear is meshed with the rack.

[0034] During the rotation of the second cam, when the raised portion of the second cam abuts against the rack, the rack moves vertically downward and the third spring is compressed. When the raised portion of the second cam no longer abuts against the rack, the rack is reset under the action of the third spring and moves vertically upward; therefore, the rack can perform vertical reciprocating motion.

[0035] During the vertical reciprocating motion of the rack, the rack is meshed with the third gear, so that the third gear can rotate forward and reverse; during the rotation of the third gear, the bidirectional screw rotates synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The specific implementation process is as follows:

[0058] When it is necessary to construct the road, a number of guardrails 1 are attached to each other in sequence and form a circle to protect the construction site; the motor 9 is started again, and the drive shaft 10 is driven to rotate by the output shaft of the motor 9; during the rotation of the drive shaft 10, the annular tube 3 rotates synchronously under the action of the connecting rod 11; during the rotation of the annular tube 3, the water inlet and the water outlet 5 can be continuously intermittently connected, so that the water in the annular water tank 2 can flow into the annular tube 3 under the action of the booster pump, and then sprayed out through the atomizing nozzle 6; during the spraying of water mist by the atomizing nozzle 6, since the annular tube 3 can rotate, the atomizing nozzle 6 can make a circular motion, thereby expanding the scope of action of the atomizing nozzle 6, enhancing the effect of the atomizing nozzle 6, allowing the water mist to diffuse over a large area, ensuring that the water mist contacts more dust, thereby achieving dust reduction and improving dust reduction efficiency, that is, improving the comfort of the construction environment and protecting the life and health of construction workers and pedestrians.

[0059] During the rotation of the annular tube 3, the rotating shaft 12 rotates synchronously; during the rotation of the rotating shaft 12, the first gear 33 moves synchronously; during the movement of the first gear 33, the first gear 33 is engaged with the annular rack 32, and then the first gear 33 rotates; during the rotation of the first gear 33, the rotating shaft 12 rotates synchronously, that is, the rotating shaft 12 can rotate while the rotating shaft 12 makes a circumferential motion; during the rotation of the first gear 33, the first gear 33 is engaged with the second gear 34, and then the second gear 34 rotates, and during the rotation of the second gear 34, the rotating shaft 14 rotates synchronously.

[0060] During the rotation of the rotating shaft 14, the second cam 29 rotates synchronously; during the rotation of the second cam 29, when the raised portion of the second cam 29 abuts against the slider 30, the slider 30 moves vertically upward, and the second spring 31 is compressed. When the raised portion of the second cam 29 no longer abuts against the slider 30, the slider 30 is reset under the action of the second spring 31, and the slider 30 moves vertically downward; therefore, the slider 30 can perform vertical reciprocating motion; during the movement of the slider 30, the extrusion block 8 moves synchronously.

[0061] When the extrusion block 8 moves vertically upward, when the extrusion block 8 contacts the rubber tube 7, the extrusion block 8 continues to move, thereby causing the rubber tube 7 to deform; during the deformation of the rubber tube 7, the water outlet of the rubber tube 7 will be squeezed and become smaller, thereby increasing the pressure in the rubber tube 7, that is, the water mist sprayed by the atomizing nozzle 6 can increase the effective distance of the water mist after the rubber tube 7 is deformed; when the extrusion block 8 moves vertically downward, the rubber tube 7 gradually returns to its initial state, thereby causing the effective distance of the water mist to gradually return to its initial state; therefore, through the deformation of the rubber tube 7, the effective distance of the water mist can be continuously adjusted, so that the water mist can contact more dust during the period of changing the effective distance, further expanding the effective range of the water mist, and ensuring that the dust is more comprehensively and fully reduced.

[0062] To sum up, through the rotation of the atomizing nozzle 6 and the deformation of the rubber tube 7, the scope of action of the water mist is expanded and the effective distance of the water mist is increased, that is, the effect of the atomizing nozzle 6 is comprehensively enhanced, so that the dust reduction of the atomizing nozzle 6 is more complete and thorough, which greatly improves the environment of the construction site, reduces the harm of dust to construction workers and pedestrians, and improves the practicability of the device.

[0063] During the rotation of the shaft 12, the fan blades 13 rotate synchronously; during the rotation of the fan blades 13, the effective distance of the water mist and the effective range of the water mist can be further increased, so that the water mist can further contact more dust, thereby making the dust reduction effect of the water mist on the dust more significant, that is, shortening the dust reduction time and improving the dust reduction efficiency.

[0064] Moreover, during the rotation of the fan blades 13, the dust in the air can be dispersed, so that the dust does not accumulate, the proportion of dust in the air is reduced, and the air quality is improved; at the same time, it is beneficial to the circulation of air in the construction site and enhances the ventilation effect, that is, the flow rate of water mist and dust is increased, and the dust removal time is shortened.

[0065] During the movement of the annular tube 3, the piston cylinder 16 moves synchronously driven by the water inlet pipe 19; during the movement of the piston cylinder 16, the first cam 15 rotates synchronously driven by the rotating shaft 14; during the rotation of the first cam 15, when the raised portion of the first cam 15 abuts against the piston block 17, the piston block 17 moves vertically downward, and the first spring 18 is compressed. When the raised portion of the first cam 15 no longer abuts against the piston block 17, the piston block 17 is reset under the action of the first spring 18, and the piston block 17 moves vertically upward; therefore, the piston block 17 can perform vertical reciprocating motion.

[0066] During the vertical reciprocating motion of the piston block 17, the piston block 17 can continuously extract and discharge the water in the annular tube 3; during the pumping of water by the piston block 17, the water in the annular tube 3 flows into the piston cylinder 16 along the water inlet pipe 19 and is temporarily stored; during the drainage of water by the piston block 17, the water stored in the piston cylinder 16 is discharged along the drainage pipe 20.

[0067] Through the above-mentioned movement, the water discharged from the drain pipe 20 has a certain force and forms a water line, which can disperse the dust in the air, so that the dust no longer gathers in a pile, and then allows the dust to diffuse, thereby increasing the contact area between the water mist and the dust, so that the dust can be better reduced by the water mist and the water line, thereby enhancing the dust reduction effect and ensuring that the dust can be completely removed; and, since the piston cylinder 16 can rotate, the range of action of the water line is expanded, ensuring that the dust in the air can be dispersed more comprehensively and fully, that is, the dust reduction time is shortened and the dust reduction efficiency is improved.

[0068] To sum up, under the joint action of the atomizing nozzle 6 and the drain pipe 20, the dust reduction effect can be comprehensively improved, ensuring that the dust in the air can be handled more thoroughly, greatly improving the working environment of the construction workers, and ensuring the life and health of the construction workers and pedestrians.

[0069] During the rotation of the second cam 29, when the raised portion of the second cam 29 abuts against the rack 36, the rack 36 moves vertically downward and the third spring 37 is compressed. When the raised portion of the second cam 29 no longer abuts against the rack 36, the rack 36 is reset under the action of the third spring 37 and moves vertically upward; therefore, the rack 36 can perform vertical reciprocating motion.

[0070] During the vertical reciprocating motion of the rack 36, since the rack 36 is meshed with the third gear 38, the third gear 38 can rotate forward or reverse; during the rotation of the third gear 38, the bidirectional screw 21 rotates synchronously; the bidirectional screw 21 rotates forward or reversely, and the two nut seats 23 can approach or move away from each other along the length direction of the guide rod 22; during the movement of the nut seat 23, the connecting block 24 moves synchronously; during the movement of the connecting block 24, the arc block 25 moves synchronously, that is, the two arc blocks 25 can also approach or move away from each other; during the period when the two arc blocks 25 approach each other, since the arc block 25 is in contact with the water outlet of the drain pipe 20, the arc block 25 can block a part of the water outlet of the drain pipe 20, until the two arc blocks 25 are in contact, and then the two arc blocks 25 move away from each other.

[0071] Through the above-mentioned movement, while the arc block 25 blocks the water outlet of the drain pipe 20, the pressure in the drain pipe 20 will increase, thereby making the effective distance of the water line sprayed from the drain pipe 20 farther, so that the water line can disperse more accumulated dust, further ensuring that the dust will not accumulate together, and at the same time greatly expanding the contact area between the water mist and the dust, comprehensively enhancing the dust reduction effect of the water mist on the dust, and improving the dust reduction efficiency on the dust.

[0072] During the movement of the nut seat 23, when the rack 36 moves vertically downward, the rack 36 squeezes the linkage block 39 through the pressing block 40, so that the vertical block 26 moves vertically downward, and the fourth spring 41 is compressed. When the rack 36 moves vertically upward, the vertical block 26 is reset under the action of the fourth spring 41, and the vertical block 26 moves vertically upward; therefore, the vertical block 26 can perform vertical reciprocating motion.

[0073] During the vertical reciprocating motion of the vertical block 26, the horizontal block 27 moves synchronously; during the movement of the horizontal block 27, when the horizontal block 27 moves to the position of the water outlet of the drain pipe 20, the horizontal block 27 can slap the sprayed water line, so that the movement trajectory of the water line changes, and then the water line can make a wave-like motion of swinging up and down, so that the water line can be dispersed; after the water line is dispersed, the range of action of the water line is increased, so that the water line can disperse more dust gathered together, further expanding the contact area between dust and water mist, thereby ensuring that the dust can be dispersed more comprehensively and fully, further enhancing the dust reduction effect on dust, and improving the dust reduction efficiency.

[0074] During the rotation of the rotating shaft 14, the drain pipe 20 is driven to rotate through the belt 28; during the rotation of the drain pipe 20, the drain pipe 20 has a certain centrifugal force; therefore, the water line will fly farther under the action of the centrifugal force, further expanding the scope of action of the water line, on the one hand, improving the utilization rate of the water line and enhancing the effect of the water line, on the other hand, ensuring that more accumulated dust can contact the water line, expanding the contact area between the dust and the water mist and the water line; that is, ensuring that the dust in the air can be handled more comprehensively and thoroughly.

[0075] To sum up, through the joint action of the arc block 25, the transverse block 27 and the belt 28, the water outlet effect of the drain pipe 20 can be comprehensively enhanced, that is, the water outlet range of the drain pipe 20 is expanded and the water outlet distance of the drain pipe 20 is increased, so that the dust in the construction site can be fully affected by the drain pipe 20, thereby ensuring that the dust can be completely removed by the water mist after spreading, thereby improving the environment of the construction site and protecting the lives and health of construction workers and pedestrians.
